Can't manage to succesfully UV unwrap house to get aligned brick textured walls
Found that wrapping the UV map around the edge is the easiest way to get the bricks to line up. You just need to concentrate on the sides. Generally a sill covers the bottom layer and on the top - you can cheat more.



The image above shows the normal map which is used later to bump the texture...



...and this shows another building with rounded brick corners.

Some textures I made from baking walls of mesh bricks. Others I drew and composed in Gimp. You can see some of the trials here on the BlenderArtists thread.

Update: First step is to make sure your seams are marked for the unwrap - CTRLE if you haven't done that already. (You can see them marked red and just in the corners.) Then U to unwrap. I use Project from View as I think it's the quickest to get neat UV's, and then just scale ...



Select the recessed edges and scale them on the X axis in the UV editor...



These are the active buttons in the UV editor...
